When the reenforced fibrous structure has thus been formed, the mandrelis collapsed sufficiently to enable it to be withdrawn through one endof the barrel structure. The construction and use of the mandrel is notdescribed as it isa known piece of apparatus. When the mandrel has beenwithdrawn, heads 16 and 17 are secured to the ends of the barrelstructures. These heads are formed of a metal having a lining 18 ofimpregnated paper or other suitable material. The outer peripheral edgesof the heads are shaped to form annular recesses 19 into which theopposite ends of the barrel stave structure may be inserted. The head isthen secured to the staves 13 by means of rivets 20 passing through thestaves and the peripheral walls of the recesses 19 and drawing the wallsof the recesses tightly against the fibrous structure enclosing thestaves. Two rivets are preferably used for each stave symmetricallyspaced near the side edges as shown in Fig. l. Bung openings 21 and 22may then be formed in the barrels and head respectively.. Hoops 23 and24 may also be placed on theouter surface of the barrel, if desired, forgreater strength.

The bilged metal stave structure may be formed in any suitable manner toprovide the bilge form and the longitudinally extending openings 14. Asillustrated, in Figs. 3 to 6 inclusive, blanks 25 of proportionate widthand length are cut or stamped from sheet metal and then curved and bentor stamped to give them the required stave shape. That is, the blank iscurved transversely as indicated at 26 in Fig. 6 and curvedlongitudinally as indicated at 27 inrFig. 5. When staves thus curved andassembled in a circular or cylindrical fashion with the side edges inabutment near their ends, the edges of adjacent staves diverge frompoint ofcontact toward the center of the stave as indicateddiagrammatically in Fig. 4.

The Youter surface of the barrel may be protected and strengthened bymeans of sheet metal surface plates 28 and 29 placed between the hoops23 and 24, and the outer edges of the heads 16 and 17 respectively. Thiscovering sheet conforms in shape to that of the surface of the containerand iits the latter. They serve to protect the outer surface of fibrousmaterial from abrasion as well yas to strengthen the structure. Theiruse, however, is optional.

Through the above invention, a barrel or container is formed which hasshaped staves having a rigidity, strength and toughness inherent incurved or rounded bilge sheet metal, and, therefore, capable ofwithstanding the shocks and stresses inherent in dropping the barrel orcontainer on its chimes as is customary in handling barrels. The fibrousstructure formed integrally through the openings 14 and covering bothsides of the staves provides a surface to which coating materials suchas paraii'in, wax or pitch, readily and permanently adhere, while at thesame time it forms an integral non-separable structure with the staves13. While `the container has the strength of a metallic structure, ithas less heat conductivity and, therefore, chilled liquids may beexposed to warm temperature for a considerable time without undesirablechanges in the temperature. l

Various modifications may be made by those skilled in the art withoutdeparting from the following claims.

What I claim is:-

1. A container having bilged metal staves in barrel formation, the sideedges of said staves contacting at their ends and separating in theintermediate bilged portion and a iibrous structure covering the innerand outer faces of said staves and uniting to an integral structurethrough the ,spaces betwen the separated intermediate edges of saidstaves.

2. A container having metal staves in barrel formation, the side edgesof said staves contacting at their ends and separating intermediate saidends, aA fibrous structure on the inner and outer'faces of said stavesand uniting to an integral structure through the spaces between theseparated intermediate edges of said staves, heads having peripheralrecesses receiving the ends of said staves and means securing the staveends in said recesses.

3. A container having metal staves in barrel formation, the side edgesof said staves contacting at their ends andseparating intermediate saidends, a paper-wrapping on the inner and outer faces of said staves anduniting to an integral structure through the spaces between theseparated intermediate edges of said staves, heads having peripheralrecesses receiving the ends of said staves and means securing the staveends in said recesses.

4. A container having metal staves in barrel formation, the side edgesof said` staves contacting at their ends and separating intermediatesaid ends, a paper wrapping impregnated with an adhesive material on theinner and outer faces of said staves and uniting to an integralstructure through the spaces between the .separated intermediate edgesof said staves, heads having peripheral recesses receiving the ends ofsaid staves and means securing the stave ends in said recesses.

5. A bilged container having a bilged sheet metal structure, the endsthereof being peripherally continuous and having widening spaces fromnear the ends to the central part of the container between stave areas,and fibrous wrappings on the inner and outer faces of said metalstructure, said wrappings being cemented together through said spaces.

6. A container having bilged metal staves in barrel formation, the sideedges of said staves contacting at their ends and separating in theintermediate bilged portion andpaper wrappings covering the inner andouter faces of said staves and uniting to an integral structure throughthe spaces between the separated intermediate edges of said staves. l

7. A container having metal staves in barrel formation, the side edgesof said staves contacting at their ends and separating intermediate saidends, a fibrous structure on the inner and outer faces of said stavesand uniting to an integral structure through the spaces between theseparated intermediate edges of said staves, heads having peripheralrecesses receiving the ends of said staves and means securing the staveends in said recesses, hoops on the outer surface of said fibrousstructure and protecting metal plates extending between said hoops andthe heads of said container.
